T-Level DPDD: Pattern Recognition Quiz

What is one of the pillars of computational thinking?

• Random guessing

• Pattern recognition

• Memorization

• Trial and error

What is a pattern in the context of programming problems?

• A. A unique solution to a specific problem

• B. Something that repeatedly occurs in many different programming problems

• C. A random occurrence in a program

• D. A one-time event in a program

What is the purpose of recognising patterns in programming?

• A. To create unique solutions for each problem

• B. To save time by reusing solutions for similar problems

• C. To make programs more complex

• D. To avoid using any pre-existing solutions

What can you do once you have identified a pattern in a program?

• Ignore it

• Speculate whether it can be reused in your existing program

• Delete the pattern

• Change the pattern randomly

What can examining a pattern help you identify?

• The color of the program

• The size of the program

• Any software or hardware components you might need

• The speed of the program

A login system uses pattern recognition. What is the first step in identifying the login pattern?

• A user must input a username and password

• The inputs are compared to the data stored in a database

• If the inputs match the user is logged into the system

• The user must input a security question

What happens if the inputs match the data stored in the database in a login system?

• The user is logged into the system

• The user is logged out of the system

• The user is asked to input the data again

• The system crashes

Which of the following is necessary to store usernames and passwords?

• A. A user interface

• B. A database

• C. A loop

• D. An algorithm

What is required to connect the interface code to the database?

• A. A user interface

• B. A loop

• C. Some means of connection

• D. A password

What should be implemented if the user gets their username or password wrong?

• A. A user interface

• B. A database

• C. A loop

• D. A connection
